A new study in the journal Pediatrics found sodiumintake among kids ages 8 to 18 averaged 3387 mg aday, and those children with the highest levels of sodium 1 consumption were twice aslikely to have elevated or high blood pressure. Rober Bazell reports.

儿科》杂志新研究表明,8至18周岁未成年人每日平均盐摄入量严重超标,而盐摄入量最高的那部分未成年人患上高血压的风险是健康同龄人的两倍。


  高盐饮食使得口腔唾液分泌减少,更利于各种细菌和病毒在上呼吸道的存在;其次,高盐饮食后由于盐的渗透作用,可杀死上呼吸道的正常寄生菌群,造成菌群失调,导致发病;第三,高盐饮食可能抑制粘膜上皮细胞的繁殖,使其丧失抗病能力。


  营养学家建议,1至6岁的幼童每天食盐不应超过2克,1周岁以前以每日不超过1克为宜,3个月后的婴儿可适当吃些咸食。小儿膳食中应该加食盐,只是尽量避免过多。对患有心脏病、肾炎和呼吸道感染的儿童,更应严格控制饮食中的盐摄入量。建议用“餐时加盐”的方法控制食盐量,既可以照顾到口味,又可以减少用盐。
